The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

Most operational amplifiers (op amps) have input and output electrostatic discharge (ESD) protection diodes, as shown in Figure 1. These diodes are designed for protection from ESD damage during ...

An optimal way to determine an op amp's input capacitance. Steps involved in making the input-capacitance measurement. 1. With a series resistor at the op-amp input, the input capacitance of the op ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

A few months ago, I wrote a Signal Chain Basics article titled “3 considerations when selecting an op amp.” While that article is very useful for selecting operational amplifiers (op amps) for new ...

Q. Why buy an expensive comparator when an op amp is just as good? A. Because it isn't. My advice to anyone tempted to use an operational amplifier (op amp) as a comparator is the same as Mr. Punch's ...
